So on the end of each module there is a Positive, Negative and center tap.
Let me pull out my soap box...
Do not allow the terminals to short!!!
REALLY BAD S#*T CAN HAPPEN if you accidentally short these!
Also as you assemble your pack you need to be mindful of the orientation of these terminals and where your B+ and B- will be located. I start with 2 modules with Negative terminal on top, then two positive on top and so on. If your building a seven module pack then you would alternate each module.
